An environmental change causes the

Biology
1 answer:
Feliz [49]3 years ago
5 0

Answer:

The correct option is<u> slight increase in salt concentration in the </u>

<u>environment.</u>

Explanation:

The main function of contractile vacuole in the body of a paramecium is to pump out excess water. But an increase in salt concentration in the environment will let the water move inside the cell by osmosis. Hence, the contractile vacuole will not perform its function and will not be able to regulate osmoregulation.

Other options are incorrect because slight changes in the temperature or pH won't affect the contractile vacuole and it will still be able to perform its function.

Provide thorough details of how human population, interplanar, and extraplanar conditions contribute to global climate change.
lawyer [7]

Answer:

all i know is the one for the human population part shown in explanation by

ryuvrajsingh1298 ....

Explanation:

Population growth is also important because it affects the Earth's ability to withstand climate change and absorb emissions, such as through deforestation as land is converted for agricultural use to feed a growing human population. We are currently adding more than 80 million people a year to our global population.

So were is the genetic material find in a prokaryotic cell
tiny-mole [99]
Endomembrane system -- not in prokaryotes
cytoskeleton -- a structural part of cytoplasm sometimes occurrent in prokaryotes
mitochondria -- not in prokaryotes 
nucleus -- if this is a "membrane-bound" nucleus, then definitely not in prokaryotes
cytoplasm -- this is the fluid that houses everything in the cell membrane
flagella -- little "tail" for locomotion, so no
cilia -- similar to flagella, little feelers usually for locomotion 
ribosomes -- these make protein using amino acids
chloroplasts -- not in prokaryotes
membrane -- just a casing surrounding a cell or organelle
organelles -- general word for the parts of a cell that perform various functions
cell membrane -- just the casing for the cell, not where genetic material's located
<span>nucleoid --- ding ding ding :-) this is it; a nucleoid is the genetic material which is loosely existing in the cytoplasm of a prokaryotic cell</span>

How have scientist started to study relationships between different groups of organisms?
Delicious77 [7]
<h2>Answer:</h2>

The scientist started to study relationships among various groups of organisms <u>C. by using genetic analyses</u>.

<h2>Explanation:</h2>

The following features were used to study about the relationships between different groups of organism:

  • External morphology
  • Similarities in structure
  • Genetic analysis
  • Chemical composition

The molecular similarities in the structure of RNA, DNA, and proteins help to establish the relationship of relationships between different groups of organisms. This was studied through testing the samples obtained by organisms using genetic analyses.
